Why is my payroll double posting?

Welcome to the Community, @greg120. I'll share some information about a double entry with your payroll in QuickBooks Online.

I recommend checking the transactions by running the Audit Log Report.

Here's how:

1. Go to Reports.
2. Look for a Business overview.
3. Choose Audit Log.

Once you've confirmed that the Audit Log contains a duplicate entry, deleting this can fix the issue. Follow the instructions below.

1. Click the Payroll tab from the left menu.
2. Select Employees list.
3. Under Run Payroll, select Paycheck List.
4. When necessary, change the date range. Then select the paycheck you want to delete.
5. Click Delete.
6. Mark the tick box to confirm the deletion. Then, click Delete Paycheck.

In addition, you can run payroll reports to double-check the correctness of your transactions.

I'll be here to assist you if you have any further questions or need assistance with your payroll management. Have a great day.
